' To all whom it may concern it appertains to make and use-the same.

This invention relates more particularly to collapsible boats intended for use as a life boat to be carried by another vessel for emergency use. v

The objects of the invention are to provide a boat which will be seaworthy but may be made to occupy less space while carried upon another vessel; to provide a boat in which the hull remains'intact so as to ride upon the water without leaking, and provided with means for increasing the depth of the boat; to prevent collapsing of the boat while in use; to provide a struc ture admitting of quick assembly or opening into operative position; to secure rlgidity and simplicity of construction, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings in which like numerals of reference indicate similar parts throughout the several views,

Figure 1 is a plan of aboat embodying my invention, shown in open position;

Fig. 2 is a longitudinal sectional view thereof;

Fig. 3 is a similar sectional view the boat collapsed;

Fig. 4 is a cross section showing the boat in open position;

Fig. 5 is a similar cross-sectional view showing the boat collapsed;

- Fig. 6 is a perspective view of a portion of the boat, showing the same in open position, and

Flg. 7 is a similar perspective view of a modified construction of boat.

In the specific embodiment of the invention illustrated in said drawing, the reference numeral 1 indicates a hull the sides of which are comparatively low, so that, when resting on the deck of a larger craft, will not rise farther than necessary above said deck. This is an important considershowing at 7 in the same general direction.

ation in the present invention, as several of the boats are carried on a steamers deck piled one on top of the other, and the number which may be so carried, depends upon how manymay be piled under the davits and still not betoo high to lift the top one by the davits. At the-same time it is important to have the hull'deep enough to obtain the necessary water displacement for the boat below the usual gunwale when the boat is loaded.

The effective depth of the boat is increased-by meansof extension side walls 2, 2 and extension end walls 3-, 3. As shown, the side and end walls are hinged to the upper edge or gunwale of the hull, and adapted to swing, inwardly for collapsing theboat. It mayherebe noted that the side walls 2, 2 are arranged to be swung up into. openpositionafter the end walls and thus hold the end walls in open position until the side walls are again swung down.

The'side walls are in turn held in open or upright position by a plurality of transverse seats 4 which may be swung up into operative position after the end and side walls have been swung to open position. The accomplishment of this feature is shown obtained by mounting each seat upon a crank 5. Said crank is preferably a rod extending longitudinally of the seat beneath the same and attached rotatably thereto by suitable bearings 6, the ends of the rod being bent transversely thereto and both extending, as The extremities 8 are then bent inwardly toward each other, as shown, and are rotatably mounted in suitable bearings 9 carried by a fixed part of the boat, as upon the seats 10 secured within the hull.

I have shown all of the seats 4 connected by a strip 11 preferably extending longitudinally centrally of the boat and of a width suflicient to be used as a seat if desired or necessary. This strip connecting the several seats 4 enables them all to be swung at one time, thus facilitating operation, and also holds the seats 4 all level. A further function of this strip is also to provide means for maintaining the seats in raised position. This'feature I have shown accomplished by extending the strip as at 12 so as to project through the end wall. A wedge or pin 13 is inserted through the end of said strip which projects beyond the end wall and by arranging the last seat to abut the end wall also, it will be obvious that the seats will be held in operative position. v

If preferred, the seats may be constructed as shown in Fig. 7, each seat 14: comprising portion extending longitudinally of the seat end sections 15, 15 hinged as at 16 to the hinged side wall of the boat. These end sec,- tions 15 are connected by a middle section 17. Said end sections and, middle section, are telescopically assembled, as by U shaped brackets 18 "attached to ,the middle section and embracing the end sections which are free to slide :betweensaid brackets and middle section. Anysuitable means may be employed for maintaining the seat extended, by dropping a pin or nail 19 into registering holesin the middle and end sections.

It is to beobserved in both constructions above described'that the seats 4: or l lare in oneplane and high enough to conveniently seat the oarsmen, and below theuplane'of those seats is another series of fixed seats 20, staggered with respect tothe upper seats and adapted for utilization by the passengers;

Having thus described my invention, 1 claim: a 1

i 1. A boat having a rcomplete-lhull'and a fixed seat, auxiliary sides for said hull, hinges at oneedge of each auxiliary side and hull whereby. said side's may befolded substantially the width o compactly within the boat, an auxiliary movable seat adapted to extend between said auxiliary sides and retain said sides from swinging inwardly, and a crank for supporting said auxiliary seat, said crank having a substantially the length thereof and a portion transverse to the seat near each end thereof, said crankbeing hingedly connected to both the fixed seat and the auxiliary seat,

whereby the auxiliary seat may beswung upwardly between'the auxiliary sides or may be swung rdly andper-mit said sides to collapselinwa dl a i 2. A boat havingawcomnletehull,
